4) Before a nation wide election, a polling
place was trying to see who would win.
Which choice best represents a sample?
A. A selection of voters over age 50.
B. A selection of male voters.
C. A selection of voters of different
ages.
D. All voters.

C.

Step-by-step explanation:

Not A. because that excludes people under the age of 50.

Not B. because that excludes females.

C. could be correct because it includes many different ages.

Not D. because all is not a sample.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

21/58.
